The H503 is a "flood" model, not "floody".
Semantics, I know, but you have to make the distinction with Zebralight, because they have both.
Pure flood lights are awesome for a limited range of uses at very close range(I keep an older model H30w in my basement, where I do oil changes and have an unlit storage closet), but are much less versatile than the "floody" models(H52Fw is what I use for backpacking, whether it's in the tent, or actually hiking in the dark).
Since you're being all minimalist and stuff, you probably don't want a bunch of different headlamps for specific tasks, and will be much better served by a H53Fw as a general purpose light.
